Beginning at 1 p.m. Friday, passengers boarding or exiting at the Civic Center, Convention Center, Japantown/Ayer, St. James, Santa Clara and San Antonio stations will have to use buses instead, according to the VTA.
Seventeen extra buses will be in service and VTA personnel will be at the closed stations to help commuters figure out their trips. Bus service for the affected riders will be free.
The stations will be reopened in time for the Monday morning commute.
Track is being replaced at the intersection of First and Devine streets, according to VTA. The construction will be the agency's third track replacement this year.
An estimated 4,000 to 5,000 riders use the light rail during the Friday afternoon commute, VTA officials said.
